yes driver work but 200w plus in 5 rx 470 rig.. too much i'm wainting for a new release
Just modify your bios, these drivers need a little bit tweaking but it works great 
I had some problems with bad shares after the upgrade and had to increase the voltage to get rid of it in one GPU.
But didn't see a big wattage increase.
Probably you'll have to tune the GPU up again.
But there is a Beta version from AMD already fixing this.
Use the AMD clean up utility before installing new beta version.
